Description
Hu leads a team testing fertilizer mixes that keep rapeseed yields high with less nitrogen in a 2023 field study. Blending slow-release nitrogen with ordinary fast nitrogen is the strategy. Trials used direct-seeded rapeseed at a reduced total rate.
Mid-range blends, with slow-release making up roughly a third to a half of the mix, matched the full-rate control for pods, seeds, and yield. Nitrogen use efficiency peaked at the middle blend. Soil enzyme activity and microbial biomass also rose under the blends, above all at flowering. Soil nitrogen stayed available for key growth stages. The authors recommend the middle blends under a quarter cut in nitrogen. The approach promises savings without yield loss.
